ABSTRACT
Common names of diseases are always based on their key symptoms. These symptoms are described here.
anthracnose: A characteristic lesion, which is a circular to angular, sometimes irregular sunken spot with grayish-black center and yellow margin in leaves, stems, and fruit (e.g., grapevine anthracnose). areolate mildew: Mildew growth in the area between veins on a leaf (e.g., cotton areolate mildew). big vein: A condition in which veins become enlarged (e.g., Lettuce big vein virus disease). black scurf: Black flaky or scaly matter adhering to the surface of a plant part (e.g., black scurf of potato). blackening: Intensive necrosis that leads to blackening of tissues (e.g., Potato black ringspot virus disease). blast: A disease that kills plants suddenly (e.g., rice blast). blight: A plant disease characterized by withering and shriveling without rotting (e.g., late blight of potato). blister blight: A bubblelike elevation on the surface of a diseased leaf that results in withering and shriveling of the leaf (e.g., tea blister blight). boll rot: Decay of boll, a fruit of plants such as cotton. Boll consists of a rounded capsule containing the seeds (e.g., cotton boll rot). brown rot: A condition in which decaying tissues turn brownish (e.g., potato brown rot). browning: Cell death leads to necrosis, which leads to the browning of tissues (e.g., Pea early browning virus disease). bud blight: Necrosis of buds (Groundnut bud blight virus disease).
